Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ticket issuing device for separating a ticket from continuous paper and issuing a ticket.

[0002]

2. Description of the Related Art In a ticket issuing apparatus of this type, a continuous paper, which is formed by connecting a plurality of single-cut ticket papers at a perforation, is conveyed from a paper feeding section, and the continuous paper is provided in a cutter provided in the middle of a conveying path. Thus, the perforation is cut to form a single-cut ticket, and the ticket is further conveyed, and information based on various ticket issuing information is recorded in the magnetic processing unit and the printer unit to issue the ticket.

In such a ticket issuing device, conventionally,
An end sensor that detects the leading edge of continuous paper such as a light transmission type sensor is provided in the middle of the conveyance path to the cutter, and if this edge sensor detects the leading edge of the continuous paper during transportation of the continuous paper, a predetermined time elapses. The conveyance of continuous paper was stopped, and at that position, the cutter was driven to separate the single-cut ticket paper from the continuous paper at a position facing the perforation.

[0004]

However, although the position of perforations for separating the cut sheet from the continuous paper is defined by a predetermined standard, it is difficult to form accurate perforations on the continuous paper. In reality, there are variations in the positions of perforations due to a bundle of continuous paper as a manufactured product. For this reason, in the ticket issuing device as described above, since the continuous paper is uniformly conveyed for a predetermined distance from the edge detection timing, if there is a misalignment in the perforations of the continuous paper, it shifts from the cutter facing position. There is a risk that the cutter will be driven in the wrong position.

Further, in a ticket issuing device which needs to issue an airline ticket or the like at a high speed, there is a great demand for reducing the number of defective cuts as much as possible. It is also necessary to eliminate this as much as possible to improve the cutting accuracy of cut sheets.

[0006] Therefore, the present invention is a ticket issuing device which can accurately separate the ticket paper even if there are variations in the perforation positions due to the manufacture of continuous paper, and therefore can reduce the number of defective cut tickets as much as possible. Is to provide.

[0007]

The invention according to claim 1 is
Continuous paper, which is made by connecting a plurality of single-cut ticket papers at the perforation for cutting, is fed out from the paper storage unit, and the continuous paper is conveyed along the conveying path, and the continuous paper is fed by a cutter provided in the middle of the conveying path. In a ticket issuing device that separates a single-cut ticket sheet from a sheet and issues a ticket by performing a predetermined recording on the ticket sheet, a sheet conveying unit that conveys the sheet along a conveying path and a continuous sheet by driving a cutter. Cutter driving means for separating the ticket paper, paper detecting means provided in the middle of the conveying path for conveying the continuous paper to the cutter, and outputting a detection result according to the passing condition of the continuous paper, and detection from the paper detecting means A paper presence determination unit that determines whether or not the detection result from the paper detection unit is a paper detection output by comparing the result with a paper detection output when there is a preset paper, and this paper presence determination Means for paper detection output If it is determined that the paper is detected, the detection result from the paper detection means is compared with the perforation detection output for cutting which is set lower than the paper detection output in advance, and the detection result from the paper detection means is used for the separation. A perforation determining means for cutting that determines whether or not a perforation detection output has been output, and when the perforation determining means for cutting determines that the perforation for cutting has been reached, the output timing of the detection result The continuous paper is conveyed by a predetermined distance, the conveyance is stopped, and the cutter driving means drives the cutter to separate the leading paper from the continuous paper.

According to a second aspect of the present invention, prior to the ticket paper separation processing of the continuous paper by the ticket paper separation control means, the paper detecting means has a separation perforation or the same degree as the separation perforation. When the ticket paper having the perforations is conveyed, the separation perforation judgment means is set in advance even if the continuous paper or the ticket paper is conveyed for a predetermined distance after the detection result of the paper detection means becomes the paper detection output. If it is not judged that the cut perforation detection output is obtained, the cut perforation detection output is lowered by a predetermined level and the perforation detection is tried again, and the cut perforation determination means outputs the cut perforation detection output. The ticket issuing device according to claim 1, further comprising: a cut perforation detection output setting means for setting again the perforation detection output at that time as a cut perforation detection output when the judgment is made.

[0009]

In the invention according to claim 1, the continuous paper is fed out from the paper storage unit and is conveyed along the conveying path. At this time, when the leading edge of the continuous paper passes through the paper detecting means, the detection result of the paper detecting means rapidly changes to a paper detection output, and the paper presence determining means determines that there is continuous paper. Subsequently, when the continuous paper is conveyed and the cut perforation of the continuous paper passes through the paper detection means, the detection result of the paper detection means temporarily changes from the paper detection output to the cut perforation detection output. The cutting perforation determining means determines that the perforation is a perforation. When the separating perforation judging means judges the separating perforation, the continuous paper is further conveyed by a predetermined distance from the output timing of the detection result and the conveyance is stopped, and the cutter is driven by the cutter driving means to drive the continuous paper. Cut off the first sheet of paper.

In the invention according to claim 2, when the continuous paper or the ticket paper is conveyed to the paper detecting means before the ticket paper separating processing of the continuous paper, the detection result of the paper detecting means is the paper detection output. After that, when the continuous perforation paper or the ticket paper is conveyed for a predetermined distance and the separation perforation determination means does not determine that the preset perforation perforation detection output is obtained, the separation perforation detection output is set to a predetermined level. When the perforation is detected again and the perforation is detected again, and the perforated perforation determining means determines that the perforation detection output has been obtained, the perforation detection output at that time is set again as the perforation perforation detection output. On the basis of the cut perforation detection output set in this way, the paper cut processing of the continuous paper is performed by the paper cut separation control means.

Detection voltage setting control for setting V and perforation detection voltage DV to appropriate values is performed.

That is, the CPU 31 first determines in ST (step) 1 whether or not the detection voltage setting mode has been set by operating the operation panel 39, for example. At this time, when it is determined that the detection voltage setting mode has been set, in ST2, the transport motor 22 is driven to drive the transport rollers 9, 10, and 11, and the continuous paper is fed from the designated bin of the bins 1. The sheet is conveyed to the delivery conveying path 2.

Subsequently, in ST3, the successive approximation reference voltage preset to a level between the voltage level when the paper sensor 26 is out of paper and the voltage level when the paper is present is applied to the successive approximation reference voltage generation circuit. Output from 48.

Then, in ST4, it is judged whether or not the output voltage from the paper sensor 26 is continuously higher than the reference voltage for successive comparison. That is, it is determined whether the paper sensor 26 detects the continuous paper 19.

At this time, if it is determined that the output voltage of the paper sensor 26 is equal to or lower than the successive approximation reference voltage even after being conveyed for a predetermined time, the sequence controller 49 controls the successive approximation reference voltage generation circuit 48 in ST11. A signal is supplied to lower the successive comparison reference voltage by one step.

If the state in which the voltage detected by the paper sensor 26 is higher than the reference voltage for successive comparison continues in ST3, the output voltage from the paper sensor 26 is stored in the RAM 33 as the paper detection voltage CV in ST5. . Thus, the setting of the sheet detection voltage CV is completed.

Next, in ST6, a control signal is supplied to the successive comparison reference voltage generation circuit 48 via the sequence controller 49 to raise the successive comparison reference voltage by one step,
This is used as the perforation detection voltage, and at ST7, the paper sensor 2
It is determined whether 6 has become temporarily lower than the perforation detection voltage. That is, it is determined whether or not perforations are detected.

At this time, when it is judged that the paper sensor 26 is higher than the perforation detection voltage, the carry motor 22 is driven in ST12 to carry the carry rollers 9, 10 ,.
11, the continuous paper 19 is returned and conveyed.

Then, in ST13, the reference voltage for successive comparison is increased by one step, and in ST14, the carry motor 22 is driven in the forward direction to drive the carry rollers 9, 10, 11 to re-feed the continuous paper 19. Then, the process returns to ST7.

On the other hand, if it is determined in ST7 that the paper sensor 26 is temporarily lower than the perforation detection voltage, this output voltage is changed to the perforation detection voltage D in ST8.
It is stored in the RAM 33 as V. Thus, the setting of the perforation detection voltage DV is completed (separated perforation detection output setting means).

Subsequently, in ST9, the carry motor 22 is reversed to drive the carry rollers 9, 10 and 11, and the continuous paper 19 is returned and carried to complete the detection voltage setting process. When it is determined in ST1 that the detection voltage setting mode is not set, the normal ticketing process shown in FIG. 7 is performed in ST10. That is, the CPU 31
First, in ST21, the host computer 38 waits for a ticket issuing command. At this time, if it is determined that the ticket issuing command is received, the transport motor 22 is driven in ST22 to transport the transport rollers 9, 10, 11
Is driven to feed the continuous paper from the designated bin among the bins 1 to the feeding path 2.

Subsequently, in ST23, it is determined whether or not the output voltage from the paper sensor 26 is larger than the paper detection voltage CV. At this time, when it is determined that the output voltage has become higher than the paper detection voltage CV, it is determined at ST24 whether the output voltage from the paper sensor 26 has become lower than the perforation detection voltage DV. That is, it is determined whether or not the first perforation 20d is detected.

When it is determined that the first perforation 20d has been detected, the next second perforation 2 is detected in ST25.
It is determined whether 0e is detected. If it is determined that the second perforation 20e has been detected, the third perforation is performed in ST26.
It is determined whether or not the perforated line 20f has been detected (separation perforated line determination means).

At this time, if it is determined that the third perforation 20f is detected, the conveyance of the continuous paper 19 is stopped by controlling the conveyance motors 22 and 23 after the conveyance for a predetermined distance in ST27, and then in ST28. To drive the cutter motor 21 (ticket paper separation control means).

At this time, the third interval between the ticket papers of the continuous paper
The perforation 20f is positioned at a position facing the cutter hole 2a. Then, the cutter 3a moves forward to pass through the cutter hole 2a, the continuous paper is cut at the third perforation 20f, and the single-cut ticket paper 20 is cut off.

When the cutting process by the cutter 3a is completed, the carry motor 23 is driven in ST29.
Then, the transport rollers 12 and 25 are driven to cut the single-cut ticket paper 20 separated from the continuous paper into the magnetic encoder unit 4.
Transported to

Thereafter, in ST30, the subsequent ticket issuing processing is performed. For example, a single-cut ticket paper 20 is attached to the magnetic encoder unit 4.
Is transported, processing such as writing predetermined information of magnetic encoded data to the magnetic stripe is performed. After that, the ticket paper 20 is conveyed to the printer unit 5 and subjected to predetermined printing, and then discharged as a ticket to the stacker 6 or 7 to end the normal ticket issuing process.

In this way, a predetermined ticket is issued, and the above-mentioned processing is repeated each time the ticket issuing command is received.

In this embodiment having such a configuration, when the detection voltage setting mode is set by operating the operation panel 39, the continuous paper is fed from the designated bin to the feeding path 2 and the successive comparison reference is used. Output voltage.

Then, even if the paper sensor 2 is conveyed for a predetermined time,
When the output voltage of 6 is less than the reference voltage for successive approximation,
The presence / absence of a sheet is detected by lowering the successive approximation reference voltage step by step, and when the state of being continuously higher than the successive approximation reference voltage becomes continuous, this output voltage is stored in the RAM 33 as the sheet detection voltage CV. Thus, the paper detection voltage C
The setting of V is completed. As described above, by setting the sheet detection voltage CV for each bundle of continuous sheets 19, it is possible to accurately determine the presence or absence of sheets.

Next, the successive comparison reference voltage is increased by one step from the currently set sheet presence detection voltage to detect perforations, and when the sheet sensor 26 temporarily becomes lower than the perforation detection voltage, This output voltage is stored in the RAM 33 as the perforation detection voltage DV. Thus, the setting of the perforation detection voltage DV is completed.

As described above, since perforations are detected for each bundle of continuous papers 19 and the perforation detection voltage DV is set, even if there are variations in the perforations of the continuous papers 19 due to manufacturing, this is not the case. Can be accurately detected.

With reference to this paper presence detection voltage,
Since the perforation detection voltage is searched by increasing the reference voltage for successive comparison step by step from this voltage, the perforation detection voltage DV can be set in a relatively short time.

In this embodiment, the continuous paper 19 is used.
Although the paper detection and perforation detection are performed while conveying the paper in the forward direction, the present invention is not limited to this, and the paper presence detection and perforation detection can be performed even when the paper is conveyed back. The voltage may be set. By doing so, the detection voltage can be set in a shorter time.

Next, when performing a normal ticket issuing operation, when the ticket issuing command is received, the continuous paper is delivered from the designated bin to the delivery path 2. When the output voltage from the paper sensor 26 becomes higher than the paper detection voltage CV, it is determined that there is paper and the first perforation is detected. Then, when the first perforation 20d is detected, the next perforation is detected, and when the third perforation 20f is detected, the continuous paper 19
Is conveyed for a predetermined distance, and then the conveyance is stopped.

At this time, the third interval between the ticket sheets of the continuous sheet is
The perforation 20f is positioned at a position facing the cutter hole 2a. Then, the cutter 3a moves forward to pass through the cutter hole 2a, the continuous paper is cut at the third perforation 20f, and the single-cut ticket paper 20 is cut off.

By utilizing the fact that the output voltage of the paper sensor 26 temporarily lowers at the perforations of the continuous paper 19 as described above, the perforations are directly detected and the ticket paper 20 is cut based on the detection timing. Continuous paper 19 is used to control the separation.
Even if there are variations in the perforation position due to the manufacturing of the sheet, it is possible to accurately separate the ticket paper.

In addition, the perforation is directly detected and the ticket paper 20
Since the separation is performed, the deviation of the cut position of the continuous paper 19 does not accumulate, and the positioning accuracy up to the cut position can be improved.

Therefore, it is possible to reduce the number of defective cut sheets as much as possible, and to eliminate paper jams.

In this embodiment, the paper sensor 2
Although the light-transmitting sensor is used as the reference numeral 6, the present invention is not limited to this, and the paper sensor 26 has a perforated detection voltage that is temporarily different from the detection voltage when the paper is present. However, a light reflection type sensor may be used.

In this embodiment, the combination of the successive approximation voltage generating circuit 48, the sequence controller 49, and the comparator 47 is used for perforation detection, but the invention is not limited to this. not,
Perforation detection may be performed using an A / D converter or the like.

Further, in the present embodiment, while the successive comparison voltage is lowered from the sheet detection voltage step by step,
Although the perforation detection is performed to set the perforation detection voltage, the perforation detection voltage is not necessarily limited to this, and the perforation detection may be performed from any voltage. However, the perforation detection voltage may be set by performing perforation detection.

[0079]

As described in detail above, according to the present invention, even if there are variations in the perforation position due to the manufacture of continuous paper, the ticket paper can be accurately cut off, and therefore, a defective cut ticket can be obtained. It is possible to provide a ticket issuing device that can be reduced as much as possible.

Further, even if there is a manufacturing variation in the shape of perforations on the continuous paper, this can be accurately detected.

When it is determined that the detection result from the paper detection unit is compared with the cutting perforation detection output that is set lower than the paper detection output in advance, the detection result from the paper detection unit is Before Cutting perforation judging means for judging whether or not the perforation for cutting perforation has been detected, and output of the detection result when the perforation judging means for cutting separates the perforation for cutting. The continuous paper is further conveyed from the timing by a predetermined distance, the conveyance is stopped, and the cutter drive means drives the cutter to separate the leading paper sheet from the continuous paper. Characteristic ticket issuing device. 2. Prior to the ticket paper separation processing of the continuous paper by the ticket paper separation control means, the paper detecting means is provided with continuous paper having a perforation or a perforation similar to the perforation. When the paper sheet is carried and the detection result of the paper detection unit becomes a paper detection output, the separation perforation determination unit is preset even if the continuous paper or the paper sheet is conveyed for a predetermined distance. When it is not determined that the cut perforation detection output is obtained, the cut perforation detection output is lowered by a predetermined level and the perforation detection is tried again, and the cut perforation determination means becomes the cut perforation detection output. 2. The ticket issuing device according to claim 1, further comprising: a cut perforation detection output setting means for resetting the perforation detection output at that time as a cut perforation detection output.
